New genetic loci link adipose and insulin biology to body fat distribution

Body fat distribution is a heritable trait and a well-established predictor of adverse metabolic outcomes, independent of overall adiposity. To increase our understanding of the genetic basis of body fat distribution and its molecular links to cardiometabolic traits, here we conduct genome-wide association meta-analyses of traits related to waist and hip circumferences in up to 224,459 individuals. We identify 49 loci (33 new) associated with waist-to-hip ratio adjusted for body mass index (BMI), and an additional 19 loci newly associated with related waist and hip circumference measures (P < 5 × 10−8). In total, 20 of the 49 waist-to-hip ratio adjusted for BMI loci show significant sexual dimorphism, 19 of which display a stronger effect in women. The identified loci were enriched for genes expressed in adipose tissue and for putative regulatory elements in adipocytes. Pathway analyses implicated adipogenesis, angiogenesis, transcriptional regulation and insulin resistance as processes affecting fat distribution, providing insight into potential pathophysiological mechanisms.

Directional dominance on stature and cognition in diverse human populations

Homozygosity has long been associated with rare, often devastating, Mendelian disorders1, and Darwin was one of the first to recognize that inbreeding reduces evolutionary fitness2. However, the effect of the more distant parental relatedness that is common in modern human populations is less well understood. Genomic data now allow us to investigate the effects of homozygosity on traits of public health importance by observing contiguous homozygous segments (runs of homozygosity), which are inferred to be homozygous along their complete length. Given the low levels of genome-wide homozygosity prevalent in most human populations, information is required on very large numbers of people to provide sufficient power3, 4. Here we use runs of homozygosity to study 16 health-related quantitative traits in 354,224 individuals from 102 cohorts, and find statistically significant associations between summed runs of homozygosity and four complex traits: height, forced expiratory lung volume in one second, general cognitive ability and educational attainment (P < 1 × 10−300, 2.1 × 10−6, 2.5 × 10−10 and 1.8 × 10−10, respectively). In each case, increased homozygosity was associated with decreased trait value, equivalent to the offspring of first cousins being 1.2 cm shorter and having 10 months’ less education. Similar effect sizes were found across four continental groups and populations with different degrees of genome-wide homozygosity, providing evidence that homozygosity, rather than confounding, directly contributes to phenotypic variance. Contrary to earlier reports in substantially smaller samples5, 6, no evidence was seen of an influence of genome-wide homozygosity on blood pressure and low density lipoprotein cholesterol, or ten other cardio-metabolic traits. Since directional dominance is predicted for traits under directional evolutionary selection7, this study provides evidence that increased stature and cognitive function have been positively selected in human evolution, whereas many important risk factors for late-onset complex diseases may not have been.

Christian Gottlob Neefe and the Bonn National Theatre, with New Light on the Beethoven Family

When the Bonn stage was closed after the death of Elector Max Friedrich in 1784, the director of its theatre company, Gustav Friedrich Wilhelm Großmann, decided to leave the city to further his career elsewhere in the Rhinelands. During the next few years, he was kept informed about developments in Bonn by two of his erstwhile colleagues, Christian Gottlob Neefe and Nikolaus Simrock, whose correspondence paints a vivid picture of musical life in the city during the later 1780s. The new Elector, Maximilian Franz, permitted a visiting troupe to perform during Carnival each year, but repeatedly delayed the decision to re-establish a resident troupe. In 1787 Christoph Brandt, a singer in the Bonn Hofkapelle, attempted a home-grown initiative, perhaps to test the market for a new permanent company. Although this failed almost immediately, a single, well-attended public rehearsal of Monsigny’s Le Déserteur was given, in which Johann van Beethoven made what was probably his last stage appearance. In a letter dated 14 May 1787, Simrock rated his performance ‘zimlich gut’. In the event, a new Bonn troupe was not recruited until 1789, when it featured the young singer Magdalena Willmann. Neefe and his musical colleagues were relieved finally to be able to resume their theatrical careers.

Memory mixed with desire : a preliminary study of philosophy and literature in the works of Friedrich Nietzsche and Milan Kundera

Memory Mixed with Desire: A preliminary study of Philosophy and Literature in the works of Friedrich Nietzsche and Milan Kundera Robert Spinelli Brock University, Department of Philosophy This thesis studies intertextuality in the works of Friedrich Nietzsche and Milan Kundera through the primary themes of memory and forgetting. The thesis starts with two introductory chapters that delineate memory according to Nietzsche and Kundera respectively. From here, I move into a discussion of Nietzsche's Ubermensch as an example of the type of forgetting that Nietzsche sees as a cure for the overabundance of memory that has led to Christian morality. Next, I explore the Kunderan concept of kitsch as the polar opposite of what Nietzsche has sought in his philosophy, finishing the chapter by tying the two thinkers together in a Kunderan critique of Nietzsche. The thesis ends with a chapter devoted to the Eternal Return beginning with an exegesis of Nietzsche's idea and ending with a similar exegesis of Kundera's treatment of this thought. What I suggest in this chapter is that the Eternal Return might itself be a form of kitsch even in its attempt to revalue existence.

Les capitaines des troupes de la Marine de 1683 à 1739 : la carrière militaire en Nouvelle-France

En 1683, la monarchie française expédie en Nouvelle-France trois compagnies d’infanterie de la Marine afin de mettre un terme à la guerre contre les Iroquois qui menace la colonie sous juridiction de la Marine. Ce premier contingent se montrant incapable de mater l’ennemi, le roi envoie d’autres compagnies dirigées par des officiers qui détiennent soit une expérience dans le service de la Marine ou dans les régiments d’infanterie. La guerre dorénavant ouverte avec les colonies britanniques, force l’enracinement de ce corps d’armée au Canada. Les administrateurs vont l’appeler troupes de la Marine. Un autre facteur d’enracinement est la permission que les autorités royales accordent aux nobles de la colonie canadienne de s’engager dans le corps d’officiers. Les Canadiens y deviennent majoritaires quelques décennies plus tard. Plusieurs de ces officiers, notamment nés en colonie ont fait l’objet de biographies. Quelques études se sont penchées sur le corps d’officiers en tant qu’acteur social. Cependant, l’ensemble de la carrière militaire d’un officier des troupes de la Marine en Nouvelle-France n’a jamais été abordé. Les capitaines, étant parvenus au sommet de la hiérarchie des troupes de la Marine avant 1739, constituent le sujet de cette recherche. Ce sera donc les grandes étapes de leur expérience militaire coloniale que l’on tentera d’approfondir tout en prenant en considération le lieu de naissance de l’officier, ce qui nous permet dégager certaines tendances relatives à la carrière d’officiers militaires dans la société d’Ancien Régime.

Self-organized sociopolitical interactions as the best way to achieve organized patterns in human social systems: going beyond the top-down control of classical political regimes

La monografía presenta la auto-organización sociopolítica como la mejor manera de lograr patrones organizados en los sistemas sociales humanos, dada su naturaleza compleja y la imposibilidad de las tareas computacionales de los regímenes políticos clásico, debido a que operan con control jerárquico, el cual ha demostrado no ser óptimo en la producción de orden en los sistemas sociales humanos. En la monografía se extrapola la teoría de la auto-organización en los sistemas biológicos a las dinámicas sociopolíticas humanas, buscando maneras óptimas de organizarlas, y se afirma que redes complejas anárquicas son la estructura emergente de la auto-organización sociopolítica.

O negro na literatura sob a perspectiva filosófico-literária de Friedrich Nietzsche e Bruno de Menezes: civilização, religião e corpo

A temática do negro na literatura tem ocupado cada vez mais espaço nas discussões e debates em torno da questão da valoração da cultura negra no Brasil, especialmente no que tange a aspectos tais como o desmascaramento de determinados estereótipos há muito alicerçados, mas, acima de tudo, tem assumido particular relevância o papel da resistência negra, que ora analisamos a partir da perspectiva de um viés social, perpassando os enfoques histórico, religioso e cultural. Cada um desses enfoques adiciona uma importância diferente para a presença negra na poesia de Bruno de Menezes, nosso objeto de investigação, daí ser possível deduzir, o que acreditamos ser de fundamental importância, não nos subtrairmos a nenhuma das abordagens ressaltadas. A obra que doravante analisaremos intitula-se Batuque, do poeta supracitado, obra esta responsável por inscrever no contexto da literatura amazônica, e mais que isso, no seio da cultura de cunho nacional, um novo capítulo, isto é, uma nova perspectiva acerca da condição do negro na sociedade brasileira. Aliando-se a essas perspectivas, acrescentaremos o ponto de vista do filósofo alemão Friedrich Nietzsche, como arcabouço teórico para as problematizações que pretendemos levantar no decorrer do texto. A presente pesquisa teve por objetivo investigar a influência do processo civilizador europeu versus negro e os cerceamentos (culturais/religiosos) decorrentes dessa influência, assim como as consequências negativas que incidirão sobre a perspectiva que o negro tem acerca de seu próprio corpo e lugar na cultura, muitas delas também provenientes da visão de mundo cristã que lhes foi imposta.

Taxonomia das espécies brasileiras de Lauraceae coletadas por Carl Friedrich Philipp Von Martius de 1817 a 1820

CARL FRIEDRICH PHILIPP VON MARTIUS foi um naturalista alemão que visitou diversas regiões brasileiras, sobretudo a região da Amazônia. Este veio ao Brasil junto com a comitiva da Arquiduquesa Leopoldina da Áustria, que aqui vinha se casar com o Príncipe Herdeiro D. Pedro de Alcântara, futuro Imperador do Brasil. A sua viagem pelo Brasil teve início em 1817, no Rio de Janeiro, e término em 1820, na região amazônica. Estima-se que coletou amostras de cerca de 7.200 espécies de plantas, que foram base para a produção da Flora Brasiliensis, editada inicialmente por ele, com a colaboração e edição póstuma de AUGUST WILHELM EICHLER e IGNATZ URBAN. Esta obra monumental foi publicada entre 1840 e 1906, com a participação dos mais eminentes botânicos europeus da época, que realizaram os tratamentos taxonômicos de 22.767 espécies brasileiras, na maioria angiosperma. O tratamento das Lauraceae ficou a cargo do botânico suíço CARL DANIEL FRIEDRICH MEISSNER. Dentre as espécies de Lauraceae constam 64 táxons com indicação de coletas realizadas por MARTIUS. Tomando-se por referência o tratamento de MEISSNER, bem como as demais opera principes, o presente trabalho teve como objetivo a atualização taxonômica das espécies de Lauraceae coletadas por MARTIUS no Brasil. Para tanto, foram verificadas as coleções dos principais herbários europeus e norte americanos, com base na literatura especializada e nos bancos de dados disponíveis. Através de imagens em alta resolução dos espécimes, esses foram confrontados com os protólogos e revisões dos gêneros. Desta forma, os tratamentos das espécies envolvidas foram conduzidos com a verificação do status taxonômico das mesmas, suas sinonímias, nomes atualmente aceitos como corretos, bem como sobre as tipificações relacionadas. Sempre que pertinente, foram feitos comentários sobre as coleções e sobre problemas taxonômicos e nomenclaturais detectados. Com este trabalho...

Early repolarization, left ventricular diastolic function, and left atrial size in professional soccer players

Recent data have suggested a relation among long-term endurance sport practice, left atrial remodeling, and atrial fibrillation. We investigated the influence of an increased vagal tone, represented by the early repolarization (ER) pattern, on diastolic function and left atrial size in professional soccer players. Fifty-four consecutive athletes underwent electrocardiography, echocardiography, and exercise testing as part of their preparticipation screening. Athletes were divided into 2 groups according to presence or absence of an ER pattern, defined as a ST-segment elevation at the J-point (STE) > or =0.1 mm in 2 leads. For linear comparisons average STE was calculated. Mean age was 24 +/- 4 years. Twenty-five athletes (46%) showed an ER pattern. Athletes with an ER pattern had a significant lower heart rate (54 +/- 9 vs 62 +/- 11 beats/min, p = 0.024), an increased E/e' ratio (6.1 +/- 1.2 vs 5.1 +/- 1.0, p = 0.002), and larger volumes of the left atrium (25.6 +/- 7.3 vs 21.8 +/- 5.0 ml/m(2), p = 0.031) compared to athletes without an ER pattern. There were no significant differences concerning maximum workload, left ventricular dimensions, and systolic function. Univariate regression analysis revealed significant correlations among age, STE, and left atrial volume. In a stepwise multivariate regression analysis age, STE and e' contributed independently to left atrial size (r = 0.659, p <0.001). In conclusion, athletes with an ER pattern had an increased E/e' ratio, reflecting a higher left atrial filling pressure, contributing to left atrial remodeling over time.

Nachhaltige Geschichte. Festschrift für Christian Pfister

Nachhaltigkeit, Klimawandel und Umweltschutz sind zu festen Bestandteilen der politischen und medialen Agenda geworden. Als Christian Pfister in den 1960er Jahren mit den Wechselwirkungen zwischen Mensch, Umwelt und Raum in Berührung kam, wurden diese Fragen noch kaum diskutiert. Mit seinen Forschungen zur Geschichte des Klimas, der Naturkatastrophen, der Energie und des Verkehrs bewies er ein feines Gespür für zukunftsweisende Themen. Als einer der ersten Historiker wagte er sich an eine Verknüpfung von klimatischen, wirtschaftlichen, sozialen und demographischen Prozessen, deren Bestandteile er später zu einer Wirtschafts-, Sozial- und Umweltgeschichte zusammenfügte. Seine Forschung ist der nachhaltigen Entwicklung verpflichtet: der ökologischen und sozialen Verträglichkeit sowie der wirtschaftlichen Effizienz. Dieses «magische Dreieck» dient Christian Pfister als Interpretationsrahmen, der seinen Blick auf die Vergangenheit beeinflusst und seinen Forschungen sowohl innerhalb als auch ausserhalb der Geschichtswissenschaft eine nachhaltige Wirkung verschafft hat.
